Clouds will continue to spread across much of the region today.
With the clouds and the east to northeast winds, highs today will
be cooler than those of Saturday and Sunday. Highs today are going
to range from the 30s across the northland and much of Minnesota
to the lower 50s in southern Iowa.

The east to northeast winds will continue to spread a cooler
airmass across the Upper Midwest tonight. Clouds are going to
